1.8T 20V 92.8MM Stroker Forged Piston Set

The Integrated Engineering IE Spec Mahle 1.8T 20V 92.8MM Stroker Piston Set is engineered as an ultimate solution for both street and track performance applications, building upon Mahle's renowned features and OEM-like wear characteristics. These pistons are recommended for high-performance engine builds requiring unparalleled strength and longevity. Constructed from Mahle's proprietary 142P alloy, these durable forged pistons offer low-expansion properties similar to 4032 alloy and strength approaching 2618 alloy. This composition allows for tight piston-to-wall clearances, ensuring quiet and smooth OEM-like operation. The set includes German steel ultra-strength wrist pins rated for over 800 HP, hard-anodized ring lands to prevent micro-welding, and Mahle's Grafal anti-friction skirt coating that reduces wear and noise. An accumulator groove is machined beneath the top ring lands to collect blow-by gasses, reducing pressure between rings, minimizing ring flutter, and ensuring a secure seal. This piston set is available exclusively in an 83mm bore, which, when paired with a 92.8mm crank, increases displacement to 2008cc. This allows for precise block boring and honing to achieve optimal results for the 2.0L stroker configuration. The 9.25:1 compression ratio is ideal for a wide range of applications, from mild street use to high-horsepower builds. This part requires a 2mm overbore and is specified for the Volkswagen 337/20AE model with the 1.8T engine.
